IMPROVEMENT IN LAMPS.

WILLIAM H. SANGSTER, OF CHICAGO, ILLINOIS-4s Letters-Patent No. 60,068, dated November 27,1866. I

SPECIFI'QATIONa Be it known that 1, WILLIAM H. SANGSTER of the city of Chicago, in the countyof Cook, and State of Illinois, have invented a new and useful Improvement in Lamps, Lanterns, and Chandeliers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification. y l

The nature and object of my invention are to produce an improved lamp, lantern, or chandelier, in which kerosene oil is burned, which will produce aolear, white fiame, free from smoke, and without the use of a chimney. A leading item of expense in the 'use of kerosene oil for illuminating ;purposes is the chimney This improvement does away with this. expense. I

Figure 1 represents a plane elevation of my improvement applied to a lamp. Figure 2 represents a top view of the mechanism employed.

Figure 3 represents a side view of the mechanism with a portion of the cylinderremoved in whichis placed the blower.

Figure 4 is a top view of the mechanism taken through the line a} x, fig. 3. a Similar letters of reference refer to similar parts in the different figures.

a a, fig. 1, represent the exterior of an ordinary lamp. 6 is the oil pot around ,whichpasses the exterior,

a a, of the lamp. At the upper partof the oil pot b any ordinary wick tube desired can be used. This oilpot is suspended within the exterior a a by any means that would suggest itself to any one. skilled in the art of making lamps. I do nolwconfine myself to the use of the exterior a a, as that is known and in use. Suitable and convenient tubes leading from the blower to the wick tube can be employed with .the same effect, andby the use ,of these tubes I am able to use a glass oil pot, which is prefer able to a metallicone. At the top ofthe exterior a a is placed a cone, -ex tending above the wick tube, as shown in fig. 1. cci s a mechanism placed at the base of the lamp. The mechanism is composed of a coiled spring, located within the drum f, a series of cog or toothed wheels, and small pinions, also cogg ed or toothed, with two or more band-wheels and belts. id is a cylinder in which revolves the blower. 2' is a sheave located on the shaft t; around this sheave and the 1 sheave 'v, on the shaft h, passes the belt a. e is a tube ex tending from the cylinder d up through the standard of the lamp to or near the oil pct 12. g is the blower, located at-one end of the shaft h. Ila-will be seen that the mechanism c c resembles in many respects'that used in the ordinary clock, with the addition of bandwvlreels and belts. The blower g is constructed with inclined fans, so that in its revolutions itforces the air upwards. k,-fig. 1, is the key used in winding the spring. It-is inserted through a hole, m, in the exterior of the lamp,

and fits upon the end n of. the shaft, to which is attached one end of the spring withinthe drum f. The mach 1 anism a cis held to its proper place within the base of the lantern by means of. the springs o o, and can be p r j readily removed by unclasping the springs o o. a l

The operation of my invention isas follows: The spring within the drum f is wound up by means of the key Is. Power is thus generated, which is exerted through the series of toothed or cog-wheels and toothed .or

cogged pinions, and the band-wheels and belts upon the blower g. .The tube e, being connected with the cyliiider :1, the air put in motion by means of the blower g is directly conducted to the flame arpund the oil pot b, a thus forcing into the flame therequisite amount of oxygen to make a clear, bright, and incandescent flainc, free from smoke, and without the use of a chimney. The tube e need not at all times pass up on. the inside of the neck or standard of the lamp. The mechanism 0 a can be placed into a suitable base, upon which can beset any ordinary lamp. Surrounding theflame will be a solid cone with no perforations, as in the ordinary lamp. I

From the cylinder d of the mechanismit'o the cone surrounding the flame will. es nuz' flexible tube, through which the air is forced by means of the blower-g directly to the flame; andithus is secured a flame, clear, pure,

and free from smoke, without the used the chimney. I also use the mechanism or in a lantern with the same eflect. I properly place it in the base of a'lan'tern with proper cohduits leading from the cylinder ofthe blower to the flame, and=producea clear, perfect flame, free from smoke, and without the use of thechimney. The mechanism a a can also be used in chandeliers with the same result. I employit in connection with this method of lighting by placing it in the centre of the chandelier, and from the cylinder d of the blowerradiates a tube to each burner, which properly leads the air put in motionby the blower on to theflamathus also securing a perfect and bright flame, free from smoke, and without the use of the chimney. I also use it in connection with chandeliers and similar lighting purposes by tubing the room-or building I wish to light in the same i 1M7 aama eewgad tially as described.

way as though I were to use gas, and at the end of one tube, into which all the other tubes lead, I place the mechauism'c c, properly connected with the cylinder def the blower 9. Thus I can light many rooms with kerosene light without the use of the chimney. It will be seen that I place the mechanism 0 c on one of its longest sides, while at the opposite side is placed the blower. By placing it in this way I am able to bring my lamp within a proper size, and when 1 use it in a lantern I can make the lower part of my lantern very short. In the use of the belts and band-wheels I am able to reduce the cost of the mechanism, and'sccure greater speed to the blower, by making the pinions smaller than can he used with cogs; and also the time'the blower revolves, by once winding up the spring, is extended. I dispense with the use of the screw. on the shaft, to

which is attached the blower; thus the friction is greatly reduced between the blower and the other parts of the mechanism. disclaim the mechanism as constructed in the patents heretofore granted to one Francis B. de Keravenan. I i

Having thus described my invention, what I claim as new, and desire to secure .by Letters Patent, is-

1. The combination of the sheave i on shaft t, the sheave v on shaft h, driven by the belt 8 that carries upon one end the blower g, with the within described mechanism that supplies the power for operating the blower when used in a lamp, lantern, or chandelier, in the manner and for the purpose herein set forth.

2. The placing of the mechanism a c on its side,-substantially in the manner described.

3. Attaching the mechanism '0 c with a lamp, lantern, or chandelier, by means of the springs o a, substan- WILLIAM H. SANGSTER.
